Solar install చేసుకోవాలని decide చేసిన తర్వాత చాలా మంది అడిగే question: "నాకు ఎంత kW system అవసరం?" Wrong size choose చేస్తే — చిన్న system వేస్తే bill fully cover కాదు; పెద్ద system వేస్తే extra investment waste అవుతుంది. ఈ guide లో correct sizing method తెలుగులో.

☀️ Generation Guide — kW బట్టి

System Daily Generation (Clear Day) Monthly Generation Suitable For
3 kW 12–15 units 300–350 units 2-3 BHK, 1 AC, fridge, fans, lights
5 kW 20–25 units 500–600 units 3-4 BHK, 2 ACs, geyser, all appliances
10 kW 40–50 units 1,000–1,200 units Large house, shop/office, small factory
15 kW 60–70 units 1,500–1,800 units Factory, hospital, apartment common area

🏠 Appliance-wise Calculation

మీ daily usage ఈ formula తో calculate చేయండి:

Common appliances daily usage (hours × watts ÷ 1000 = kWh):

1.5 ton AC1,500W × 8 hours = 12 units/day
Refrigerator150W × 24 hours = 3.6 units/day
Ceiling Fan (3 nos)75W × 12 hours × 3 = 2.7 units/day
LED Lights (10 nos)10W × 6 hours × 10 = 0.6 units/day
TV (LED 40")80W × 6 hours = 0.48 units/day
Total Example≈ 20 units/day → 5 kW system

🤔 3 kW ఎందుకు Most Popular?

Telangana లో 3 kW most popular sizing reason:

Smart Strategy: Budget తక్కువగా ఉంటే — 3 kW today + 2 kW expansion later. Most inverters future expansion కి ready గా ఉంటాయి. Expand చేసినప్పుడు subsidy రాదు కానీ current capacity with subsidy maximize అవుతుంది.

📏 Roof Space Requirements

System SizeRoof Space NeededShadow-Free Area
3 kW~180 sq ft (17 sq m)6 panels × 2m × 1m
5 kW~300 sq ft (28 sq m)10 panels
